Creats my first Slack bot using Python and Django to automate routine tasks for the team. The most important part of the work is to pick accurate emoji for each bot replay to the command. ๐Ÿ˜Š๏ธ

So, my contest is over. I partially accomplish the assignment.

Successfully resolve the first task in the scope of which program should speed up comparing with an example and should write to stdout tetrahedral number for each positive integer that came from stdin.

The second task should resolve the maximum subarray problem using some algorithm, but I haven't enough time to get it done.

This is progress with test task before I can participate in course about algorithms. My head literary blowing up!

The example in C++ was written for checking my assumptions (but in general this happens accidentally) for the main program originally written on Python. ๐Ÿ˜…

Just right now we are flying away from Sweden ๐Ÿ‡ธ๐Ÿ‡ช to Ukraine on the brand new Boeing 737-800 with registration number EI-GSG if the Ryanair airlines. Itโ€™s less than half a year old! ๐Ÿ”ฅ๐Ÿ”ฅ๐Ÿ”ฅ

It looks like this is my personal record! I not flying yet on such modern planes. Before this, the youngest plane on which I flying somewhere was two and a half years old.

Today we have visited Nordiska museet museum. Nice dive into Sweden ๐Ÿ‡ธ๐Ÿ‡ช history. The museum itself is situated on the Djurgรฅrden island. Like every place in the center of Stockholm can be reached by walk (or metro if you donโ€™t like walks).

Tickets cost $15 for adults and free for children and teens under eighteen.

The museum have audio guide app that can be installed on the smartphone. This amazing and allows you to listen information on the go.

And birds! They are everywhere, especially near bridges. The funny thing that they are not afraid of the people at all and asking for food every time. ๐Ÿ˜…

The weather in Stockholm is awesome today. I really miss the sun in foggy, cold, wet and cloudy Kyiv winter. I have not seen the sunlight for more than two months, so today I'm really happy.

Also, there is no snow on the streets. Dry stone surfaces and asphalt makes me incredibly happy. I enjoying walking around the city. ๐Ÿ‡ธ๐Ÿ‡ช

This is the first European capital where I see clean water in the reservoirs and channels around the city. Looks awesome! ๐Ÿ”ฅ๐Ÿ”ฅ๐Ÿ”ฅ

WireGuard now can be downloaded from the Mac App Store. macOS users can make their systems more secure.

Iโ€™m happy that folks from WireGuard perform such a nice job and release free and nice tool for system hardening. Itโ€™s free of charge and Open Source. Enjoy! ๐Ÿ”ฅ๐Ÿ”ฅ๐Ÿ”ฅ

Basically, this is was the first thing that we saw in Stockholm when pool out ourselves from the bus. ๐Ÿ˜…

Local cops stop huge Cadillac (I think this is it) and talking with the guys in it about something.

And, you know, here a little bit cold. And those guys driving in cabriolet! Swedish men are tough indeed. ๐Ÿ’ช๐Ÿป๐Ÿ‡ธ๐Ÿ‡ช

Before our flight to Stockholm, ๐Ÿ‡ธ๐Ÿ‡ช I have ordered a special offer for roaming from my carrier. Just for $10, I will be able to consume 1.5 Gb of data (and I hope this will be LTE compatible speeds, not 3G like it were last time) abroad. I think this is awesome! ๐Ÿ”ฅ๐Ÿ”ฅ๐Ÿ”ฅ

Ha, @github forcing us to develop stuff in even more lazy way. They are introduced right now Draft Pull Requests. I think it's good so far for sharing some ideas, but most will use it definitely for not this.

BTW, since Microsoft snatch GitHub there happen good things. For example, now I'm able to use it with much more pleasure because they offer private repos for free for up tree contributors. ๐Ÿ”ฅ๏ธ๐Ÿ”ฅ๏ธ๐Ÿ”ฅ

But the advantage of Apple Music comparing Spotify is the ability to upload your own music into iCloud Music Library. For example, today, while driving to office, I listen King Crimson. Those albums are outside both streaming services, but Iโ€™ve got some CDโ€™s that was imported to my library long time ago. Unfortunately, with Spotify Iโ€™m not able to listen my old records, but with Apple Music I can.

Huh, here we go. I donโ€™t need storage sharing, but for YouTube Premium family accounts will be just what I need. ๐Ÿ˜Š

Faced funny issue on Linux. It only appears if two devices connected to the same Bluetooth headphones. After switching music on Spotify from iPhone to the laptop, sound plays a couple seconds from the headset and disappearing. The issue can be fixed by playing any sound outside Spotify on the laptop. macOS comparing Linux seems to me super-stable operating system.

And after this change was forced to move back to Spotify. Amazing streaming service. I fall in love with it because of great and precise recommendations. While using Apple Music I'm missing for a feature that allows switching playing music to the other device.

Decide to try Linux as a main OS for work. With a bit of advice from my twitter pal decide to try Pop!_OS. Looks awesome and works smoothly. System fonts look great, the material design-like theme also looks good. Laptop running Pop!_OS amazingly fast comparing with Windows setup. Already almost a month have passed, but I still enjoying my new setup. Turning on my MacBook Pro only a couple times during this period.

For some reasons yesterday Letโ€™s Encrypt certificate suddenly became untrusted in the Mail app around 11:00 AM on my iPhone X with the latest iOS version. On the iPad all works fine. Both devices running under iOS 11.2.6. The issue has been solved only by manually adding root certificate from Letโ€™s Encrypt website to the iPhone X. Can someone explain to me why this happen?

This is fantastical! After the eight years of use I have found in my vacuum cleaner Dyson DC22 the radio transmitter for powering on/off the device and the pet brush. Dyson engineers have used the batteries to avoid wires and make the machine more ergonomic. By the way, this is first battery replacement after the eight years of use. Awesome machine!
